Adding dictionary values to a list?

Question

I have the following:

 list_of_values = []    
 x = { 'key1': 1, 'key2': 2, 'key3': 3 }

How can I iterate through the dictionary and append one of those values into that list? What if I only want to append the value of 'key2'.

Answer 1

If you only want to append a specific set of values you don't need to iterate through the dictionary can simply add it to the list

list_of_values.append(x["key2"])

However, if you insist on iterating through the dictionary you can iterate through the key value pairs:

for key, value in x.items():
   if key == "key2":
      list_of_values.append(value)
